Introduction: Endoscopic full-thickness resection (EFTR) is a promising technique that allows for a minimally invasive resection of mucosal and submucosal lesions in the gastrointestinal (GI) tract. The data regarding the efficacy and safety of performing EFTR of upper GI lesions using a full-thickness resection device (FTRD) is limited. Hence, we performed a systematic review and meta-analysis of the studies that evaluated this technique., Methods: We performed a comprehensive systematic search of multiple electronic databases and conference proceedings that reported outcomes of EFTR using the FTRD system. The weighted pooled rates of technical success, complete (R0) resection, adverse events (AE), and residual or recurrent lesions were analyzed with 95% CI using the random effects model., Results: Eight studies with a total of 139 patients who underwent EFTR of upper GI lesions were included in the study. The pooled, weighted rate of technical success was 88.2% (95% CI: 81.4-92.7%, I2 : 0). The R0 resection rate was 70.7% (95% CI: 62.5-77.8%, I2 : 0). Overall AE rates were 22.1% (95% CI: 15.8-30.1%, I2 : 0), however, most of the AEs were minor. Of the patients who had follow-up endoscopies, the residual and/or recurrent lesion rate was 6.1% (95% CI: 2.4-14.4%, I2 : 0). Heterogeneity in the analysis was low., Conclusions: EFTR using the FTRD seems to be effective and safe with acceptable R0 resection rates and low recurrence rates. Further prospective studies are required to validate our results and to compare various modalities of endoscopic resection with this single-step EFTR device., (Copyright © 2022 Wolters Kluwer Health, Inc.

Background: Endoscopic ultrasound-guided rendezvous (EUS-RV) endoscopic retrograde cholangiopancreatography (ERCP) is an alternative to interventional radiology-guided rendezvous ERCP in patients who failed biliary cannulation with conventional ERCP. However, there is significant variation in reported rates of success and adverse events associated with EUS-RV-assisted ERCP. We performed a systematic review and a proportion meta-analysis to reliably assess the effectiveness and safety of the EUS-RV-assisted ERCP., Materials and Methods: We conducted a comprehensive search of multiple electronic databases and conference proceedings (from inception through August 2020) to identify studies reporting EUS-RV-assisted ERCP in patients who failed biliary cannulation with conventional ERCP techniques. Using the random-effects model described by DerSimonian and Laird, we calculated the pooled rates of technical success, clinical success, and adverse events of EUS-RV-assisted ERCP., Results: Twelve studies reporting a total of 342 patients were included in the meta-analysis. The pooled rate of technical success (12 studies reporting a total of 342 patients) was 86.1% [95% confidence interval (CI): 78.4-91.3]. The pooled rate of clinical success (4 studies reporting a total of 94 patients) was 80.8% (95% CI: 64.1-90.8). The pooled rate of overall adverse events (12 studies; 42 events in 342 patients) was 14% (95% CI: 10.5-18.4). Low to moderate heterogeneity was noted in the analyses., Conclusions: EUS-RV-assisted ERCP appears to be effective and safe in patients who failed biliary cannulation with conventional ERCP. Given the risk of adverse events, it should be performed in centers with expertise in therapeutic endoscopic ultrasound., (Copyright © 2021 Wolters Kluwer Health, Inc. All rights reserved.)

Unlabelled: Postmenopausal women with nonalcoholic steatohepatitis are at an increased risk of hepatic fibrosis compared with premenopausal women. Whether duration of estrogen deficiency in postmenopausal state dictates an individual's fibrosis risk remains uninvestigated. We assessed the associations of age at menopause and time from menopause with fibrosis severity in postmenopausal women with nonalcoholic fatty liver disease. Data from 488 postmenopausal women with (1) histologic diagnosis of nonalcoholic fatty liver disease and (2) self-reported information on age at menopause were analyzed. The associations of premature menopause (age at menopause of <40 years) and time from menopause (age at study enrollment - age at menopause, years) with fibrosis severity (stage 0-4) were assessed using multiple ordinal logistic regression models with and without adjusting for clinical confounders. Among the participants (age at menopause 43.7 ± 8.6 years), women with premature menopause (29.3%) were younger at enrollment (P < 0.001) and used hormone replacement therapy more often (P < 0.003). After adjusting for age at enrollment, race, waist circumference standardized by body mass index, current smoking, current alcohol use, hypertension, diabetes/impaired fasting glucose, homeostatic model assessment of insulin resistance, and hormone replacement therapy, premature menopause was associated with an increased likelihood of having more severe fibrosis (adjusted cumulative odds ratio = 1.9, 95% confidence interval 1.3-2.7, P = 0.001), while time from menopause was directly associated with an increased likelihood of having more severe fibrosis (adjusted cumulative odds ratio for 5-year unit = 1.2, 95% confidence interval 1.1-1.3, P = 0.002)., Conclusion: Duration of estrogen deficiency in postmenopausal state confers fibrosis risk among postmenopausal women with nonalcoholic fatty liver disease.
